Winter Driving

Driving on Snow or Ice
Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick.
Turn on Traction Control. See
Traction Control/Electronic
Stability Control 0 164.
Antilock Brake System (ABS)
improves vehicle stability during
hard stops, but the brakes
should be applied sooner than
when on dry pavement. See
Antilock Brake System
(ABS) 0 162.
Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas.
The surface of a curve or an
overpass can remain icy when
the surrounding roads are clear.
Avoid sudden steering
maneuvers and braking while
on ice.
Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby. To get
help and keep everyone in the
vehicle safe:
Turn on the hazard warning
flashers.
Tie a red cloth to an outside
mirror.
Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which

Warning (Continued)
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
Open a window about 5 cm
(2 in) on the vehicle side
that is away from the wind,
to bring in fresh air.
Fully open the air outlets on
or under the instrument
panel.
Adjust the climate control
system to circulate the air
inside the vehicle and set
the fan speed to the highest
setting. See Climate
Control Systems.
